BUNDLE-DISCHARGER FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 277,356, dated May 8,1883,

Application filed January 15, 1883.

' mechanism applicableto low-down or platform binders-that is to say,binders of the class by which the grain is delivered fromgrain-platforms to binder-tables or grain-receptacles at the inner endsof said platforms, and bound at or but slightly above the levels of thegrainplatforms, inside of and close to the drivingwheels of themachines.

Myobjeot mainlyis to provide a simply-constructed, easily-operated,strong, and durable bundle-discharger, by which bundles of grain, asbound, are lifted from the place of binding and tossed to the rear ofthe machine, each bundle as acted upon by the discharger being turnedend for end or half over, so as to cause the butts of the stalks tofirst come in contact with the ground as the bundles are in turndeposited behind the machine and out of its way when making the nextround of the field.

The accompanying drawings show those parts only of a binder illustrationof which is thought to be required to show an adaptation of my inventionto a low-down'binderin which the binder-table or grain-receptacleisarranged at about one foot above the level of the grainplatform.

Figure l is a view in side elevation, showing the parts as occupying theposition assu med just after the discharge of a bundle, this positionbeing also the normal or stationary position (if the mechanism. Fig. 2is a view in side elevation, showing the parts as in the positionassumed by them shortly before a bundleis acted on. Fig.3 is aview inside elevation, showing the parts in the position assumed by them whenabout to lift a bundle. Fig. 4 is a view in side elevation, showing theparts in the position assumed at the time of tossing or discharging abundle. Fig. 5 is a plan or top view with the parts in the position inwhich they are shown in Fig. 3. Fig. 6 is a rear elevation with theparts in theposition in which they are shown in Fig. 2.

vation, the position of the parts being as in Figs. 3 and 5.

A vertically vibrating, rocking, or turning tossing-fork is shown ascomposed of a shank, A, and two curved teeth, a b, which serve to engageand sustain the bundles while being lifted and directed toward the rearof the machine. The teeth are formed with or rigidly connected to theshank,and the shank is mounted to rock in a vertically-vibrating carrieror arm, B, pivoted near one end and supporting the fork at itsoppositeend. This arm vibrates in a plane parallel or nearly parallel with thepath of the machine. The fork-shank A is shown as mounted in bearings cc in short arms or lugs O O of the supporting-arm B. The pivot ot' thearm B is formed by a shaft, D, rocking in bearings 61 d. The arm is fastto its pivot-shaft, and is bent at its rear end, so as to form a crank,E, which is connected by a rod or link, 0, with another crank, F, on

a driving-shaft, G. This shaft G is shownas I understood that at eachrevolution of the driving-crank F the fork will be Vibrating vertically,as the arm B vibrates about its pivot D, at or near the rear end of thebinder-table or grain-receptacle, first rocking downward, and thenupward to the starting or normal position, in which it is shown inFig.1. The rocking or turning movement is imparted to the tossing-forkby means now to be described.

A spring, H, coiled about the forkshank, acts with a tendency to holdthe fork in its normal position or else to move it into this position.in the direction in which its'spring turns it is limited by a stop -lug,h, against which the tooth b strikes. (See Fig. 1.) The fork is rockedagainst the force of the spring H by means of a cam or inclined block,I, against which the tooth b strikes when the fork is vibrated forwardlyand downwardly. The cam I is at the side of the knotter-box or slottedcover J of ordinary knotting mechanism, upon which the grain rests, asbound, in usual well-known way.

Dogging and tripping mechanism, by which to temporarily'loclt the teethin their bundlesupporting position, and to release them from The rockingmovement of the fork such position after discharging abundle, consistsof a bent dog or curved-ended arm, K k, fastto the end of thefork-shank, outside its rear bearing, and a tripper bar or latch, L I,

mounted loosely on the pivot D and acted upon by a spring, m. A stop, a,on one of the lugs 0, serves to limit the movement in one direction ofthe latch, and the spring at acts with a tendency to hold the latchagainst the stop or else move it toward the stop. A stop, N, is struckat the proper time by the heel end I of the latch-bar, thus moving thelatch away from the stop a, for a purpose presently to be made apparent.

In operation, when a bundle is to be discharged, the driving-shaft isset in motion to vibrate the fork, the fork descends, a tooth passes oneach side of the knotter-box, (the center of the bundle,) and the teethare turned by the contact of one of them with the cam until they passbeneath the bundle and are locked in the position in whichthey are shownin Figs. 3, 5, and The locking of the teeth in position to lift thebundle results from the inward swing of the curved ended dog, and thedepression by it of the spring-latch, until, when the dog has swungentirely across the latch, this latch springs up behind the dog andprevents its reverse swing. (See Fig. 7.) The quick elevation of thebundle by the rapid movement of the fork upwardly and toward the rear ofthe machine next takes place until the position represented in Fig. 4 isreached, by which time the bundle,ha-ving been brought over or somewhatin rear of the pivot of the supporting-arm, is tossed from the fork witha motion of revolution about the center of vibration of -the fork, suchas to turn the bundle end over and cause the butt-end of the bundle-theend farthest from said center-to first come in contact with the groundbehind the machine, so avoiding injury to the heads of the grain. Afterthe discharge of a bundle the heel end of the latch strikes the stop N,thus vibrating the latch against its spring and releasing the dog.Immediately upon the release of the dog the spring of the fork-shank 1.The combination, substantially as hereinbefore set forth, of thebinder-table', the ver- 'tically-vibratin g arm, pivotally supported ator near'the rear end of the binder-table, means rocking about andsupported by the arm for engaging and sustaining the bundles, and meansfor vibrating the arm upwardly and rearwardly to discharge the bundlesbutts first upon the ground in the rear of the machine.

2. The combination, substantially as here inbetore set forth, of thevertically-vibrating supporting-arm, the rocking fork carried thereby,means for turning the fork to present its teeth beneath a bundle,dogging mechanism by which the teeth are locked against turning whilelifting and tossing a bundle, and means by which the supporting-arm ismoved upwardly and rearwardlyindischargingabundle, for the purposedescribed.

3. The combination of the binder-table, the vertically-vibrating arm,the rocking fork supported thereby, and the cam for turning the fork topresent its teeth beneath a bundle, substantially as and for the purposehereinbefore set forth.

4. The combination of the vertically-vibrating arm, the rockingbundle-tossing fork supported thereby, the pivot of the arm, the crankthereon, the connecting-rod, and the drivingcrank, substantially as andfor the purpose hereinbefore set forth.

5. The combination of the vertically-vibratin g arm, the rocking forksupported thereby, the spring by which the fork-teeth are turned in onedirection, and the cam by which the teeth are turned in the oppositedirection, substantially as and for the purpose hereinbefore set forth.

6. The combination of the vertically-vibrating arm, the rocking forksupported thereby, the spring by which the fork-teeth are turned in onedirection, the stop for limiting the movement imparted to the teeth bythe spring,the cam acting to turn the fork-teeth against the forceoftheir spring, and the fork dogging and tripping mechanism,substantially as and for the purpose hereinbefore set forth.

.7. The combination of the vertically-vibrating arm, the spring-actuatedrocking fork sup ported thereby, the dog secured to the forkshank, thespring-latch acted upon by the dog, and serving, in connection with it,to lock the fork-teeth while acting on the bundle, and the stop againstwhich the end of the latch strikes to tree the fork-teeth, substantiallyas and for the purpose hereinbefore set forth.

8. The combination of the driving-crank, the vertically-vibratingfork-supporting arm, its pivot, the crank thereon, the connecting-rod,the spring-latch vibrating about the pivot of the fork supporting arm,the stop against which'the end of the latch strikes, the springactuatedrocking fork, and its dog, substantially as and for the purposehereinbefore set forth. v

In testimony whereof I have hereunto subscribed my name.
